There hasn't been an IP ban since the beginning of September. Try restarting your cable modem, it might've assigned you the same ip as someone else who was banned from a while ago who happens to use the same ISP as you.

There are some which start with 125. but none which goes on with 168. You must have bad luck to get one of those banned IPs but I guess I could remove all banned IPs for once or make the list a bit more compact.
